In Atomic's massive lineup of Hawx Ski boots built for backcountry, the Hawx Prime XTD 115 Tech Alpine Touring Boot is the stiffest option for women who want a comfortable fit. A stiff flex of 115 provides the stiffness necessary for charging steep couloirs, and the 100mm last ensures enough comfort for a full day of powder. Its Prolite shell keeps weight at a minimum while the Energy Backbone boasts better energy transmission for a greater edging performance. Both the shell and liner are thermo-moldable to customize the fit to your footshape. Gripwalk rubber pads provide solid traction when you're bootpacking to the summit, and it's compatible with tech bindings.
